10 all whom t may concern.' V

Be it known that I, FLOYD D. S'rown, of lVilmington, in the county ofNew Castle and in the State of Delaware, have invented a certain new anduseful Improvement in Bung- Presses, and do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates particularly to a machine for forming bung-holesand bunghole closures used on kegs, but has special reference to such a`machineas used in con-Y nection with steel powder kegs.,Y

The object: of my invention is t provide a machine of thev abovecharacter rwhich will automatically and continuously produce bung-holesin keg heads by punching the holes, raising bosses aroundv the holes topermit the attachment of ears, and which automatically feeds `the earsinto. the machine and rivets'or fastens the ears on the bosses formedaroundV the bun -holes soy that thereby the closures of the eg bungholesmay be readily secured to the ears. Further objects of my invention willlappcar from a consideration ofthe detailed'description thereof which isset forth` hereinvvWhile my invention iscapable of embodiment in manydifferent forms, fr the pur-V pose of illustration I have Yshown onlyone form thereof in the accompanying drawings, in which, g y f ,c Figure1 is a front elevation of a machine made in accordance Vwith myinvention, Fig. 2 is an end elevation of the same, IFig. 3 is a verticalsection taken through the same.

Irasanten July 3o, 191e.v i

In theA drawings have shown Vmain frame l, which hasatone'end a pair ofsta-l tionarybearings 2 toreceive a shafty 3 and at the other end apairV of adjustable' bearings 4 to receive a shaft 5. Each oftheadjustable bearings 4 is carried upon slide- Ways 5 located on thezmainframeV l, the

position of the b earings 4 being determined by screws 6y passing fromthe main frame to a point adjacent to the sides of the'sliding bearings4. The shafts?) and 5.V carry i'espectivelyv drums 7 and 8 to receive aflexible band 9 of metal or any Vother suitable -v material. Atintervals `along. this band 9 there are circular openings 10 toVreceiveA the openings l I eted to the face'of the band 9. In order tosecure blanks 12in place in' theopenings 10, each opening 10 hasadjacent thereto on be operated upon. VBetwee'n'theseAVA l0strengthening strips 11 arerivthe band, a pair of'tapered catches` 13 atI. one side of the openingsv 10, and a pivoted 'Y catch 14 at theV p Yother side thereof.v n Each of the catches 14 is pivotally supported: in

of theband 9 bolts'16, said of brauckf` Y immediately above the'drum v8.AsI the band now advances the Vblanks will be clampedv in positionfautomatically assoon as the catches 14' reach theV position of fa' camplate 18, whichis ylocatedat the fronti.V of the machine at one Vside ofthe band 9.:

It will be notedl that the cam plate l13 has'` at its eXtreme left endan inclined surface19 to permit vtheV catches 1 14`to lbe graduallyclosed. Said cani plate 18 is also supportedV p screws 20whichfare'loosely supported in sockets 2l in said frame, andby thefactthat 1 the side of the cam plate 18 is also supmovement portedagainst the faces vof a plurality ofV /i spring-pressedv plungers 22supported in sockets 23 in the main frame 1. The band 9 is given anintermittent movement in the'f following manner. VThe shaft 3j has a' p,ratchet 24 which'is movedV at intervals by a 80 a pair of brackets V15`connectedto the fface pawl 25 carried upon a pair o'li oscillating arms26 loosely carried by the shaft 8 on the opposite sides of the ratchet24. The pawl 25 isthus supported between the oscillating arms 26 andbearsupon the periphery of the ratchet 24. A link 27 connects theoscillating arms 26 with a lever 28 pivoted to the main frame near itscenter and having aroller 29l at the-other end thereof which coperateswith a cam. 80 secured to a counter-shaft 81, which is supported inbearings 32 upon the main frame of the machine. This counter-shaft 31carries a gear 32a which is driven from. a main driving shaft 33 havinga pulley 34, which shaft is supported in bearings 85 also on the mainframe of the machine. The application otl power is controlled by a foottreadle 35 connected by a link 36 with a lever 37 which controls aclutch 38 through a link 89. Near the center ot' the machine thecountershaft 31 has an eccentric 40 which is connected by journalbearings 41 with a sliding carriage 42. This sliding carriage 42 hasvertical slides 43 at the two sides thereof, the vertical slide 48 atthe right of Fig. 1 contacting with a ixed removable guide 44 secured tothe main frame by screws 45, while the left vertical slide 48 coperateswith an adjustable guide 46, the position of which is determined byadjusting screws 47 and fastening screws 48 `for securing the slide inthe adjusted position. Two operations are carried out by onereciprocation of the sliding carriage 42, said sliding carriage carryingdevices which operate upon two blanks located in the flexible band 9 atthe same time. The l'irst of these operations is effected by theapparatus at the left of the sliding carriage 42 which comprises a punch49 supported on a subsidiary sliding carriage 50 and adapted to beadjusted by the adjustment of said sliding carriage. In order to adjustthe sliding carriage the latter is provided at its upper end with ascrew-thread 51 to which are attached a pair of movable collars 52located above and below a portion of the main sliding cai'- riage 42.This punch 49 is so formed that it coperates with a die 53 situatedbelow the band 9 to punch out a hole in the blank for forming thebung-hole of the keg and at the same time raises a boss` around thehea-d thus punched out. The blank tlius providedwith a bung-hole andboss around the hole is then ready Jfor the next succeeding operation,that is to say, the application to the bung-hole of an ear 53a andriveting or fastening the same to the bung-hole. This is carried out bythe apparatus at the right of the sliding carriage 42. This apparatus isso constructed, however, as not to, operate except when a blank is atthe saine time in the opening immediately below the punch49, so that by`this means the apparatus for feeding in an ear 53fL and attaching thesame to the head around the bung-hole will only be caused to operatewhen there has beena blank inserted in the band 9 and previouslyoperated upon to provide a bunghole and boss around the bung-hole. Inorder to accomplish this result a vertical sliding rod 54 is adapted tocontact with a blank when Iin the opening in the band immediately belowthe .punch 49. A spring 55 upon the rod 54 normally moves the rod 54downwardly so as to` also.V move downwardly a catch or arm 56 pivoted tothe sliding carriage 42 and supported upon the .upper end of the rod 54.When there is a blank in the opening 10 immediately below the punch 49,the rod 54 will contact therewith so that upon vthe downward movement ofthe sliding carriage 42 the rod 54 and the arm 56 supported by the saine4will be moved upwardly, thus bringing the'end -o the arm 56'into aposition such as to move ahorizontal sliding rod 57 to the right ofthemachine as shown in Fig. l. This rodr57 is supported in bracketsl 58attached to thev sliding carriage 42; and a spring 59, which is attachedto one of the brackets 58, and which engages a catch 60 upon the top ofthe sliding rod 57, normally moves said rod toward ythe lett of themachine. Then the rod 57 has been thus moved tothe left of the machinethis end Vwill not extend beyond the right-hand'bracket 5,8 and said rodwill, therefore, not make any connection with the parts with whichitisadapted to cooperate. `When, on the other hand, however, the rod 57 hasbeen moved to the right of Fig. 1, owing to the presence of a blankbeneath the punch 49, the end of the rod 57 Awill extend beyond thebracket 58. In this position of the rod 57 its end will overlie aspring-pressed :catch 61 carried on the end oi'. a lever 62 pivoted tothe main frame of the machine. This lever 62 is connected at its end bymeans of a link68 to a slotted arm 64r on alever 65 which is alsopivotedl to the mainframe. The lever G5-has in addition to the arm 64gan'upwardlyfdirected arm 66 and a laterally directed arm 67. The latterarm -67 is provided for connection by means of a link 68 with a lever 69extending beneath the band 9 so as to be operated at its other end by arod or plunger 70, which extends upwardly through the center of adie-71, locatedbelow the `band 9. Said die 71 coperates with a punch 72car- `riedylupon a slidable adjustable carriager 73,

which has-at its upper end a screw-threadedextension 74 arranged foradjustment by means of collars 75 located above and below a portion ofthe sliding carriage 42, re-v spectively. The upwardly "directed arm-66has a pin 7 6 which coperates with a slot 7 6a in a lever 76b pivotedtothe main frame. This Y lever l76b has-atits upper @nda pair of slots76C which co-act with the ends of a rod 7 6d attached to a movableplateg77. The movable plate 77 is supported so as to slide upon aninclined stationary plate 78, said movable plate 77 being'connected tothe rod 76d by means of a screw 78a and spacing plate'78", which aresituated in a slot 78c near the rupper end of the plate 78. Near itscenter, the plate 77 has a pair of screws 7 8d which pass through aspacing plate 78e located in a slot 7 8l in the body of the plate 78,said screws passing into an angular guide plate 79 having inclinedforward surfacesl 80, which guide plate 79 slides upon the top of theplate 78. Near its forward end, the plate 77 carries a finger 81, havinga notch 81a similar in shape to a inger-nail upon its upper surface,which finger 81 is connected to the plate 77 by screws 81". The notch 81is provided to engage with the holes in the centers of the ears as theyare fed downwardly into the machine. The upper end of the lever arm 66is connected by a link 82 with a bar 83 extending across the entiresurface of the plate 77, said bar 83 having at'each side thereof alongitudinal rod 84 upon the upper surface of which there is a guideplate 85 located ovei the top of the plate 78. The two rods 84 areconnected together at their forward ends by a plate 86 which extendsbeneath the surface ofthe plate'77, which plate. 86 has at each endthereof a block 87 extending upwardly and along the side of the rod 84,which is adjacent thereto. Sheet metal fingers 88l are interposedbetween the ends of the rods 84 and the blocks 87 ,and screws 89 passthrough the blocks 87 and into the rods 84 so as to secure the said rods84 and fingers 88 to the plate 86. Above the plate 78 there is provideda hopper 91 fed from chute 90, which hopper is supported upon the mainframe in any suitable manner. The hopper 91 is formed with a rforwardextension 92 above the plate 78 to limit the downward movement oftheears from the hopper 91, and at the front of the extension 92 and'on topthereof, there' is a spring catch 93Vwhich is riveted to the extension92 at its upper end and which has a recess 94 at its lower end toreceive the bent end of the ear 53 which is to vbe applied tothebung-hole of the keg head.v

In the operation of my invention, heads are placed in the openings 10 inthe band 9 as said openings are brought above the top of the drum 8 inthe intermittent movement of the band, which intermittent movement iseffected by Ithe ratchet 24, the pawl 25 and' the cam 30 with connectingparts. As the band 9 passes forwardly, the catches 14 thereon come intocontact with the plate 18, thereby clamping the blanks securely inposition `in the openings 10. lVhen a blank comes below the punch; 49,the reciprocation of lthe carriage 42 causes the punch 49 tocooperatewiththe die 53 to punch out a holeV for the bung in the head of thekeg,and at the same time raise the boss around the head of the ear 53. =When`a been operated upon by and thediefefthe redeawul Zontally movable rod57 Y beyond-theend of theright-hand bracket 58. The rod 57 will thenproject into the path of the catch 61 and the next downward movement ofthe carriage 42, which will be the next movement of the carriage 42taking place after the removal of the keg head from-under the punch 49to la position under the punch 72will operate the lever 62 until the-bar57V has passed beyond the end of the catch 6l. [In this movement of thelever 62, the two lingers 88 willhave beenmovedby the linkk 82 so as topush one of the ea-rs 53a on to the keg head above the bung-hole andaround the boss formed upon said keg head and at the same time thelinger 81'. will have been withdrawn and engaged with thehole in thenext suc'-` ceeding ear 53 beingl fed downwardly in the 'hopper 91, themovement of the linger 81 being accomplished Vby the, lever' 7 6*. Afterthevlever V62 has ceased moving,vthe punch 72 coperates with the'die 71to rivet or fasten the ear 53ato the keg head by turning over the edgesof the boss uponthe top of the ear 53a to permanently fast-ein the samein place. At` the same time, the contacting of the punch 72 With'th'edie v71 will cause ,theA plunger 7 0- to move downwardly, which movementwill bring about a movement of the fingers 88 and exactly the reverse ofthe movements just described; that is to say, this movement will causethe two fingers 88 vto Vbe withdrawn from above the keg head 'and at thesame time the linger 81 will be pushed .forwardly so as to force the ear53a ear 53a springs vinto the notch 94v 'iiflthfe catch 93. Thecontinued operation'of the thejrnger 81,.

which it enga-ges to a position'in which the'foldedf edgefoftheV machinebrings about a 'continuous repetition vof these movements, whereby kegheads are provided Vwith bosses around the holes, over which ears arefed upon the bosses around the bung-holes and the'ears are riveted orfastened in position lby turning over the edges of the bosses on to thetop of the ears. The heads, as they are finished 1n the mannerindicated, are carried to the right of the machine by the bandl 9 wherethe catches 14 become released from the action of the kplate 18,whereupon the heads, with attached ears, fall away from the band so asto be removed for .nal atbung-'holes and` tachment to the kegs. The ears53 are provided to receive slides the bung-holes.

While I have described my invention above Y(not shown)` to close indetail, I wish it to be understood that inany changes may be madetherein without departing from the spirit of my invention.
